Specification of Letters Patent. Patented June, 6, 1916.

Application led J' uly 18, 1913. Serial No. 779,665.

To all whom t may concern.' Y

Be it known that I, J oHN P. GLAsHowER, a citizen of the United States, residing at Whitinsville, in the county rof Worcester and State of Massachusetts, have invented the following-described Improvementsv in The improvement concerns the means for separating and controlling the slivers in derby doublers and like machines and consists in the provision of parts as hereinafter set forth whereby the slivers are causedto enter the rolls of the winding'head with a uniform section and under uniform conditions of motion and tension whereby they are wound into better laid and larger laprolls and whereby slivers of heavier weight than heretofore can be successfully wound into lap-roll form. y

In the drawings: Figure 1 is a top plan of so much of an ordinary derby doubler as will sufice to illustrate thevmanner of application of the invention thereto. Fig. 2 is a side elevation thereof, showing also the winding drums and lap-roll spool in diagram. Fig. 3 is a longitudinal section of Vthe parts shown in Fig. 1.- Fig.'4 is an illustrative detail.

In the drawings, the numeral 1 represents the sliver table, and 2 the winding head. The former may consist of any suitable sup'- port for the slivers, being generally a polished metal plate some tenl orl more feet in length, slightly wider than the length `of the lap-roll spool, and mounted on legs so that sliver cans can beplaced beneath it.`

Two shafts marked 3, 4, are journaled 4adjacent the side margins of this plate ortable and serve Aas lcontinuous bottom rolls for a series of top rolls such as indicated at 5 in Fig. 1. The top rolls are held in place on the roll shafts by means of brackets marked 6. The slivers from the cans 7 which are disposed beneath and alongthe sides of the table, as indicated by dotted lines, are passed through guide forks 8 into the bite of the top rolls 5 upon the roll shafts 3 and 4, and are moved vor fed by the' motion of these rolls onto the flat surface of the table. 'On the latter is provided a series of guide posts 9, one for each sliver, and around which such sliver turns from the feed rolls to travel thence lengthwise of the table, so that all the slivers will move in parallelism toward the winding head. ThereV are as many of these studs 9 as 'there are slivers requiring to be turned in order to be directed in parallelism along the table, and the set of studs is staggered accordingly so that each will be substantially opposite the point of entrance of lits sliver onto the table and will direct such sliver along the table without conflict with adjacent slivers.V For brevity of illustration only part of the sliver table and only a few of the guide posts are shown condensing rolls which take theslivers from the table and forward them to the lap-spool 12, the latter being rested as usual in the crotch of the two winding drums 13 and rotated by them so as to wind the parallel, assembled, slivers into lap spool form. This also is common construction and will not require further description. Power is transmitted to the winding head in any appropriate manner and from the winding head to the feedroll shafts 3 and 4, by any suitable gearing such, for example, as the gear train indicated at 14a.

As the several parallel slivers on the table move toward the winding head, they are first subject to a preliminary condensing or flattening treatment by passing under a roller 14, which is placed at the end of the sliver table neXt to the winding head. This roller is mounted to rotate in slots in two posts 15, and is free to rise and fall therein, being held by the bottoms of the slots at a Xed minimum distance from the top of the table, and confined from escape from the slots by the linch-pins 16, inserted in the .tops of the posts.

nary condensing member the slivers pass directly into the sliver spaces between a series of thin upright and parallel separator plates 18, arranged in a transverse row across the table and in alinementV with the sliver courses, so that each sliver may pass from under the roll 14, straight to the particular sliver space provided for it. The separator plates are equally spaced apart and they are also each of the same length or size so that each sliver passes through a space of the same dimensions, and in so passing has contact with an equal surface of the plates, so that each is thus'subject to equal frictional retarding effect, which feature of the present invention is important and tovbe distinguished from ordinary sliver-lap and doubler machinesywherein the slivers near the sides of the table are subject to the most friction and greatest tension. By their contact with the separator-plates the vertical sides or edges of the slivers are flattened and smoothed out, and the cross-sections of the slivers are thus formed more or less exactlyv square or rectangular as shown in F ig. 4 before and as they pass into the receiving rolls 10. The cross-sectional dimensions of the .l slivers are also equal, and the liability of one sliver crowding and overrunning ,its neighbor on either hand is thus eectively prevented. The lap-spool therefore receives a ribbon or lap of cotton which is of uniform thickness from one margin to the other and of which each component sliver occupies its proper proportional part, and no more, of the total width of the ribbon as will be evident.

The separator plates can be variously mounted to accomplish the purpose above described, and they may be stationary if desired, but are most elicient in operation when formed as circular disks stamped out of thin saw-blade steel and mounted on a common support to move or rotate in the same direction as the sliver moves. The most convenient means of mounting them is to assemble them directly on the cross-shaft 19, which connects the feed-roll shafts 8 and 4, because this'shaft is already present in most doublers and rotates in the proper direction. The series of disks 18 and their intermediate spacer collars 20 are kept in position on this shaft by means or' two end collars 21, but the disks need not be secured fast to the shaft inasmuch as the rotation of the latter, when the disks are loosely placed thereon, will in any event cause them to rotate and the looseness of the disks does not retard the slivers.

As shown in Figs. 3 and 4, the shaft 19 is below the level of the surface of the sliver table and the slivers intersect the rotary disks above such level inthe path of a chord, and may touch the spacer collars 2() as shown. rlhc disks, as thus disposed, have a slight rubbing action on the sides of the slivers which assists in smoothing and flattening the same so as to promote the formation of a rectangular section, such as above referred to. member 14 and the series of disks 18 thus cooperate as a forming means to square up and equalize the cross-sectional shape of all the slivers. The essential principles of operation of such means however do not require the specific form of construction shown in the drawings and within the scope of the claims herein the invention is susceptible of wide variation in' respect of the geneial structure and assemblage of parts. The preliminary condensing means 14, while desirably a roll as above described, is not required to be rotatable in its supports if its under surface is sufficiently smooth, and it may therefore be constituted by a polished bar mounted in the same relation to the slivers and for'the purpose of flattening brought upward from beneath the table, a

series of parallel and equally spaced sliver separators at the delivery end of the table, and a lap winding-head beyond said separators, each of said separators presenting the same extent of frictional surface for contact with the slivers, and means'coperating with said separators to square the cross-section of said slivers as they pass to the winding-head.

2. In a doubler, a winding head and sliver table in combination with a series of thin, upright partition plates arranged parallel with each other and with the longitudinal aXis of the table, and in a row extending transversely of the table and a series of sliver guiding means on the table adapted to determine the respective courses of the several slivers whereby they enter between the plates with substantially parallel movement, and means overlying the said slivers to flatten the same and thereby square the cross-section of said slivers.

. 3. 1n a doubler, the combination of asliver table, bearing means for determining the respective courses of the several slivers brought upward from beneath the table, a plurality of separator plates at the delivery end of the table, spaced equally apart and each presenting the sainel extent of contact surface Ato the slivers separated by them, and means in advance of such plates for flattening the slivers entering between the same.

The preliminary condensing 4. In a doubler, the combination with the winding head and sliver table, of a member extending crosswise of the table and adapted to flatten the slivers moving thereon and a series of upright partition plates in rear of such member between which the slivers pass to the winding head.

5. In a doubler, a winding-head and sliver table in combination with a series of thin upright partition plates arranged parallel with each other and with the longitudinal axis of the table, and in a row extending transversely of the table, and a series of sliver posts on the table adapted to determine the respective courses of the several slivers whereby they enter between the plates with substantially parallel movement.

6. In a doubler, the combination with a winding head and sliver table, of means for guiding the slivers from the table toward the head, comprising a series of sliver separators Vadapted for movement in the direction of the sliver movement.

8. In a doubler, the combination of a sliver table and winding head, of a transversely disposed rotary shaft, a plurality of parallel disks on the shaft and means for drawing the slivers between the disks into the winding head.

9. Inadoubler, the combination of a sliver table and windingl head, of a transverse sliver table and winding head, of the feed rolls for thesliver table, atransverse shaft connecting such rolls, a series of sliver separator disks carried on the shaft and adapted to be rotated thereby, a sliver condensing member in advance of the disks, and a staggered series of sliver studs on the table, adapted to direct the slivers from the feed rolls in parallelism to the spaces between the separator disks. y
